If it doesn't work then revert to old bios.

I use ATIflash from bootable USB/SD card.


Command for flashing that I use.


atiflash -f -p 0 bios.rom

atiflash = is used first on every command
-f = force
-p= flash
bios.rom= example format of bios. BIOS name should use no more than 8 letters or numbers and end in .rom

Sapphire states that my card has 2 different BIOS on it with 1 that is designed for improved overclocking but when i opened up the BIOS information with ATIFlash both of my BIOS were the same. I contacted Sapphire and asked them to send me the 2nd bios and after about a week and a half of going back and forth in emails I was sent the newest bios that i posted in this thread and i was told that my card uses the SAME bios on both switches.


I think the marketing department at Sapphire made a mistake on the product description of the 2 different bios with my card, may be the same situation for your card.

Always back up you stock BIOS.

Your MSI TF3 BIOS #1 and BIOS #2 are not identical.


My Sapphire HD7950 950mhz edition BIOS #1 and BIOS #2 were identical.

Just isn't compatible. Flash back to working BIOS.

Flashed my orignal (blue) sapphire 7950 OC (900) with the 950 bios, so far everything seems great. My oc is still limited @ 1100ish but I no longer get random black screens and the volts required to hit that have gone down ALOT.

Will test more tomorrow.
